I suspect your option is to look for an 06! That's what I did, although it wasn't only the EB question, I wanted to go back to a long box and I had no idea the headlights on the 05's were so bad. I went to an 05 from a Sport 01 with dual headlights, and thought I'd gone blind! I now have a 3500 06, and am very happy with it ( I can see again!)
